Exit 9: RELEASE exit

Use this user exit to release any resources acquired at the RESERVE user exit. ISPF relies on task termination to release any resources reserved by the abending logical screen task. This user exit does not get control in the case of abnormal termination of the logical screen.

If your serialization mechanism is such that task termination will not release the reserved resources, an exit routine is provided at the logical screen end user exit to clean up any unreleased resources for that task.

The RESERVE done by ISPF is released before the exit routine is given control.

The RELEASE exit is still called if Configuration table keyword PDSE_RESERVE_PROCESSING is set to OFF.

Exit parameters

In addition to the standard exit parameters described in Exit parameter list, the exit routines at this user exit receive these parameters. ISPF ignores any changes made to these parameters.

qname: An 8-character field that contains the queue name against which the RESERVE is done. (ISPF uses a qname of 'SPFEDIT '.)
rname: The 44-character resource name (data set name) that is reserved.

Return codes

No return codes are acknowledged at this user exit. When this exit returns to ISPF, normal processing continues.

Note: For multiple exit routines, return codes still affect the processing flow.
